To (Mil whom at concern.-

Be it known that l, PATRICK B. DELANY, a citizen of the United States, residing at South Orange, county of Essex, State of NewJersey, have invented certain new and useful Improvements in Perforators for Telegraphic Transmitting Tapes, of which the following is a specification.

This invention relates to perforating mechanism for preparing atransmitting-tape with three rows of perforations onc lateral row for transmitting impulses of one polarity, which may represent dashes, another lateral row for transmittingimpulses of opposite polarity, that may represent dots, and a third row, preferably intermediate the other two; through which the line maybe grounded and in which the number of perforations is equal to the number in both the other rows. Such a tape may be used in the system set out in my application filed December 15, 1896, Serial No. 615,796, of which this case is a division.

In the preparation of the strip I use a perforator having three punches in line across the tape. These punches may be operated by two keydevers manually or electromagnetically. Each lever, whether the dot or dash, presses on the middle punch at the same time that it presses on its signal-punch, so that a hole is punched in the center of the tape at the same time and in the same transverse line The spacing is done by a third or center key or lever pressing upon a cross-lever carrying at its end a pawl which engagesa tooth in a ratchet-wheel at each upward motion of the key or lever and is operated by each of the punch-levers as well. This spacing-lever may be operated entirely by hand-power or in addition an electromagnet which will relieve the hand ofpart of the labor, so that but slight pressure is required. An important feature of this perforator is its ready adaptation to either the two or three row system, as it is only necessary to raise the adjustable screws of the levers to throw the middle punch out of action, the center row of holes being in no way necessary for feeding the tape either in the perforator or transmitter, as is the casein other systems.

In the accompanying drawings, Figure 1 is a plan view with one of the levers broken away; Fig. 2, a transverse section therethrough on the line 22; Fig. 3, a longitudinal. section, and'Fig. 4 a length of the perforated tape.

A is the dot-lever, B the dash-lever, and O the spacing-lever, each of which is fulcrumed at its rear end and is normally pressed upwardly by a spring A. The punching de- Vices are arranged beneath the levers between their fulcrums and end. The lever A has an inwardlyprojecting lug a, on which are mounted two adjustable screws (1 (t the former ofwhich is arranged immediately above and adapted to impact against the dot-punch a and the latter of which is arranged above and adapted to impact against a projection (4 attached to and extending laterally from the intermediate or center punch c. The dashlever has an inwardly-projecting lug 6, in which are mounted two similar adjustable screws 5' t the former of which is arranged above and adapted to impact against the punch and the latter of which is arranged over and adapted to impact against the center punch c. The punches a" c I) are arranged in a line at right angles to the length of the tape to be punched and to its line of travel. The tape is caused to pass through a suitable guide or trough under the punches and is perforated as the punches are actuated, all as is well understood. The spacing-key C is arched at the center, so as at that point to be thrown up above the punching devices, and when manipulated has no effect thereupon. When the dot-key A is depressed, the corresponding punch a is driven downwardly, as is also the center punch a, and when the dash-key B is depressed the dash-punch b is forced down, as is also the center punch 0. Thus whenever a perforation representing either a dot or a dash is made in the tape a perforation in the same transverse line with it is also made in the central part of the tape. The paper tape passes under the punches through a guideway or trough D and is drawn forward, as is presently described.

In perforating devices of this general character the tape in passing through the trough While being punched is liable to buckle or swell upwardly, and to remedy this difficulty I have heretofore formed the trough with an overhanging edge at each side to prevent the rise of the tape. This plan while partially effective is not completely so, and my present invention comprehends a new means of remedying this defect, as follows:

Two straight rods or pieces of wire (Z, formed with hooked ends engaging eyes in the frame of the instrument, lie loosely upon the bottom of the channel or trough, respectively adjacent to its edges, and the tape'is fed beneath them. They impose upon the tape a slight friction, which is useful in efl'ecting its uniform feed and also prevents its rising or buckling during its passage under the punches and through the trough or channel. Beneath the levers A C B and between their fulcrums and the punches is a pivoted horizontal lever E, normally pressed upward by a spring E and having at its end a cross-piecethat is to say, the lever is T-shaped. In this crosspiece and arranged, respectively, beneath the levers A C B, so as to be struck thereby, are adjustable screw-bolts e e 0 the center one of which, 6, extends through the lever E and is adapted to impact against a screw-bolt f, adjustably mounted in the end of a lever F, carried by a rock-"shaft F, mounted in suitable bearings.

F is an adjustable stop that impinges against a cross-bar of the frame and limits the downward excursion of the lever F. Thus whenever either of the keys A C B is depressed the lever E is forced downwardly, and it in turn through the central bolt 0, carried by it, depresses the lever F and actuates its rock-shaft. A laterally-projecting arm F attached to the rock-shaft and extending therefrom in an opposite direction from the lever F, is normally drawn downwardly by an adjustable spring F which, therefore, also controls the rock-shaft and the lever F and carries at its end a pawl f, that engages the teeth of a ratchet-wheel f on a shaft f mounted in suitable bearings. A spring f presses against this pawl, and a spring-detent or back-stop f engages the other side of the ratchet-wheel. Thus when either leverA, C, or B is depressed partial and definite rotation is imparted to the tape drawing shaft f and all the leversA C B have the same play or depth of motion. On this shaft in the center line of the trough D and beneath a pressure-wheel f is a serrated or sawtoothed wheel mounted on the shaft f over which the paper tape passes. The pressurewheel f is mounted upon a pin or stud journal projecting from an arm f rocking upon an arm or projection mounted in the frame and drawn down by an adjustable spring f In the event that it should be desired to omit the central line of perforations from the tape it will only be necessary to adjust the screwbolts (0 and Z1 so that when the keys A B are depressed these bolts will not strike against the center punch G or against the angular projection (0*, carried thereby. It will also be apparent that the mechanism for manipulating the spacing devicesthat is to say, the devices for effecting the step-by-step feed of the tape under the punches-is such that they are actuated through an equal distance at each step by the depression of the keys A C B, since the lever E imparts motion to the lever F always at the same distance from its fulcrum and of uniform extent by means of the center bolt 6. By adjusting the screws 6 or f and the adjustable stop F of the lever F the range of throw of the pawl f may be regulated and be given such extent of motion that in rising it will pass sufiiciently far enough above the next tooth of the ratchet-wheel to be engaged as to afford enough lost motion to permit the punch to leave the tape before the feed devices draw upon it.

In this construction of perforator the frame 2, carrying the punches a 0 6 may be removed at will and a corresponding part substituted whenever desired on account of the dullness of the punches or for any other reason. It is apparent that this is so because the punches are not directly connected with the devices that operate them and that the part marked 2 may be detachably connected with its base.

I claim as my invention- 1. In a telegraphic-tape-perforating machine, the combination of three punches arranged in a single line at right angles to the line of travel of the tape, a key and means associated therewith for simultaneously actuating the center punch and one only at its side, another key and means associated therewith for simultaneously actuating the remaining punch and the center punch only, for the purpose specified.

2. In a telegraphictapeperforating machine, the combination of three punches arranged in a single line at right angles to the line of travel of the tape, a key and means associated therewith for simultaneously actuating the center punch and one only at its side, another key and means associated therewith for simultaneously actuating the remaining punch and the center punch only, and a third space-key and means associated therewith for feeding the tape without actuating either of the punches.

3. In a telegraphic-tape-perforating machine, the combination of three punches arranged across the path of the tape, a dot-lever having a projection for acting upon one of the punches, and a second projection for simultaneously actuating the center punch, while the punch for forming the third line of perforations remains inactive, and a dash-lever having a projection for acting upon the remaining punch,and a projection for simultaneously acting upon the center punch while the dotpunch remains inactive.

4. In a perforating-machine, the combination of feeding devices,a lever connected therewith, the punches, levers for actuating them, a lever intermediate the feed-lever and the punch-actuating levers and engaged thereby, adjusting-screws carried by said intermediate lever, and engaging separatelythe punch-actuating levers, a central adjusting-screw carried by the intermediate lever, and an adjustable screw carried by the feeding-lever upon which the screw carried by the intermediate lever presses when eitherof the punch-actuating levers is actuated.

5. In a telegraphictapeperforating machine, the combination with the tape guide or channel and the intermittently-operated tape feeding and perfo 'ating devices, of two wires or rods loosely held in the channel and respeotively bearing upon the tape near its edges.

6. In a telegraphic-tape-perforating ma chine, the combination with the tape guide or channel, and the intermittent]y-operated tape feeding and perforating devices, of two stifl Wires or rods, each pivoted at one end and resting freely upon the tape and adapted to move about its pivot.

In testimony whereof I have hereunto subscribed my name.
